Question on WOMH Parking

Hey everyone, I will be going to a show tomorrow at WOMH (I've never been before), and when buying tickets months ago, I pre-paid for parking in Lot B. I did a quick scan on this sub, and many have said you can find free parking if you search (I probably should have done that instead, but it is what it is).

My question – for anyone who has parked in the paid lot at WOMH in the past, do they still fill up fast? Also, it looks like the pre-paid parking pass shows up on my phone – I'm assuming there's someone there to scan the digital parking pass when you pull into the lot? Just gauging what to expect parking-wise. Thanks!
